• ffmpeg streaming to rtmp at 30fps

  19 janvier 2018, par user6326558

  I am trying to stream my desktop to facebook rtmp server using screen-capture-recorder :

   -re  -rtbufsize 256M -f dshow -i audio="Mikrofon (Realtek Audio)" 
  
  -rtbufsize 256M -f dshow -i audio="virtual-audio-capturer"  
  
  -rtbufsize 1024M -f dshow -i video=screen-capture-recorder -r 30  
  
  -filter:v scale=1280:720 -c:v  h264_nvenc -pix_fmt yuv420p -preset fast 
  
  -b:v 8M -maxrate:v 10M  -c:a aac -b:a 128k -ar 44100 
  
  -f flv rtmp://live-api.facebook.com:80/rtmp/..............

  I am using h264_nvenc codec for gpu acceleration, but I can stream at only 12-18 fps. However, when I stream into a file :

   -re  -rtbufsize 256M -f dshow -i audio="Mikrofon (Realtek Audio)" 
  
  -rtbufsize 256M -f dshow -i audio="virtual-audio-capturer"  
  
  -rtbufsize 1024M -f dshow -i video=screen-capture-recorder -r 30  
  
  -filter:v scale=1280:720 -c:v  h264_nvenc -pix_fmt yuv420p -preset fast 
  
  -b:v 8M -maxrate:v 10M  -c:a aac -b:a 128k -ar 44100 
  
  D:\test.mp4 -y

  I get 30 fps without problem, even when playing game (eg. Call of duty 6, pretty HW draining). Is it also possible to stream to rtmp at 30 fps with my command configuration ? Thank you

  If needed, my ffmpeg build config is :

• ffmpeg rtmp streaming at 30fps

  19 janvier 2018, par user6326558

  I am trying to stream my desktop to facebook rtmp server using screen-capture-recorder :

  ffmpeg -re  -f dshow -i audio="virtual-audio-capturer" -hwaccel cuvid 
  
  -f dshow -i video=screen-capture-recorder  -r 30 -rtbufsize 1024M 
  
  -filter:v scale=480:360 -vcodec libx264 
  
  -pix_fmt yuv420p -preset fast -b:v 8M -maxrate:v 10M  -c:a aac -b:a 128k 
  
  -ar 44100 -f flv rtmp://live-api.facebook.com:80/rtmp/..............

  But when I start streaming, it says that fps is only 10 and sometimes it immediatelly on start-up yells following error. Then, when I start to do something on my computer, for example I run a game, I keep getting that warning 20 times per second, and streamed video is 0.5 fps.

  real-time buffer [screen-capture-recorder] [video input] too full or near
  too full (545% of size : 3041280 [rtbufsize parameter]) ! frame dropped !

  When I stream it into file,

  ffmpeg -re  -f dshow -i audio="virtual-audio-capturer" -hwaccel cuvid 
  
  -f dshow -i video=screen-capture-recorder  -r 30 -rtbufsize 1024M 
  
  -filter:v scale=480:360 -vcodec libx264 
  
  -pix_fmt yuv420p -preset fast -b:v 8M -maxrate:v 10M  -c:a aac -b:a 128k 
  
  -ar 44100 D:\test.mp4 -y

  it says streaming is 30 fps, but as soon as I start doing something, for example game, the metioned situation repeats, tens of errors, and 0,5 fps video.

  I tried chanching -rtbufsize from 8 to 2048 megabytes, nothing changed. I tried adding and disablinh hw acceleration, nothing changed. Can anyone tell me, what am I doing wrong ? Thank you

  Solved -rtbufsize 1024M must be before -i. Another thing, I rather used codec h264_nvenc from nvidia for cuda acceleration, now I can stream into file at 30 fps without problems and warnings, even while playing game (Call of duty 6, HW draining). However, when I try to stream to rtmp, I also get no warnings, but I can stream at only 15 fps. Is it also possible to stream to rtmp at 30 fps with my command configuration ?
